When there is no V magnitude, it is 154 estimated from R or B magnitude. When there is no B or V 155 magnitude, the color B-V is estimated from the other magnitudes. 156 Also proper motions of faint stars are neglected at all. 157\item Stellarium's Catalog of Variable Stars based on General Catalog of Variable Stars (GCVS) version 2013Apr. \url{http://www.sai.msu.su/gcvs/gcvs/} 158 Samus N.N., Durlevich O.V., Kazarovets E V., Kireeva N.N., Pastukhova E.N., Zharova A.V., et al., General Catalogue of Variable Stars (Samus+ 2007-2012) 159 \url{http://cdsarc.u-strasbg.fr/viz-bin/Cat?cat=B%2Fgcvs&} 160\item Consolidated DSO catalog was created from various data: 161 \begin{enumerate} 162 \item NGC/IC data taken from SIMBAD Astronomical Database \url{http://simbad.u-strasbg.fr} 163 \item Distance to NGC/IC data taken from NED (NASA/IPAC EXTRAGALACTIC DATABASE) \url{http://ned.ipac.caltech.edu} 164 \item Catalogue of HII Regions (Sharpless, 1959) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/20}) 165 \item H-$\alpha$ emission regions in the Southern Milky Way (Rodgers+, 1960) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/216}) 166 \item Catalogue of Reflection Nebulae (Van den Bergh, 1966) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/21}) 167 \item Lynds' Catalogue of Dark Nebulae (LDN) (Lynds, 1962) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/7A}) 168 \item Lynds' Catalogue of Bright Nebulae (Lynds, 1965) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/9}) 169 \item Catalog of bright diffuse Galactic nebulae (Cederblad, 1946) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/231}) 170 \item Barnard's Catalogue of 349 Dark Objects in the Sky (Barnard, 1927) (\url{http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/220A}) 171 \item A Catalogue of Star Clusters shown on Franklin-Adams Chart Plates (Melotte, 1915) from NASA ADS (\url{http://adsabs.harvard.edu/abs/1915MmRAS..60..175M}) 172 \item On Structural Properties of Open Galactic Clusters and their Spatial Distribution.

By electing to download the material from this web site 343 the user agrees: 344 \begin{enumerate} 345 \item that Caltech makes no representations or warranties with respect to 346 ownership of copyrights in the images, and does not represent others 347 who may claim to be authors or owners of copyright of any of the 348 images, and makes no warranties as to the quality of the images. 349 Caltech shall not be responsible for any loss or expenses resulting 350 from the use of the images, and you release and hold Caltech harmless 351 from all liability arising from such use. 352 \item to use a credit line in connection with images. Unless otherwise 353 noted in the caption information for an image, the credit line should 354 be ``Courtesy NASA/JPL-Caltech.'' 355 \item that the endorsement of any product or service by Caltech, JPL or 356 NASA must not be claimed or implied. 357 \end{enumerate} 358 Special Cases: 359 \begin{itemize} 360 \item Prior written approval must be obtained to use the NASA insignia logo 361 (the blue ``meatball'' insignia), the NASA logotype (the red ``worm'' 362 logo) and the NASA seal. These images may not be used by persons who 363 are not NASA employees or on products (including Web pages) that are 364 not NASA sponsored. In addition, no image may be used to explicitly 365 or implicitly suggest endorsement by NASA, JPL or Caltech of 366 commercial goods or services. Requests to use NASA logos may be 367 directed to Bert Ulrich, Public Services Division, NASA Headquarters, 368 Code POS, Washington, DC 20546, telephone (202) 358-1713, fax (202) 369 358-4331, email \url{bert.ulrich (at) hq.nasa.gov}. 370 \item Prior written approval must be obtained to use the JPL logo (stylized 371 JPL letters in red or other colors). Requests to use the JPL logo may 372 be directed to the Television/Imaging Team Leader, Media Relations 373 Office, Mail Stop 186-120, Jet Propulsion Laboratory, Pasadena CA 374 91109, telephone (818) 354-5011, fax (818) 354-4537. 375 \item If an image includes an identifiable person, using the image for 376 commercial purposes may infringe that person's right of privacy or 377 publicity, and permission should be obtained from the person. NASA 378 and JPL generally do not permit likenesses of current employees to 379 appear on commercial products. For more information, consult the NASA 380 and JPL points of contact listed above. 381 \item JPL/Caltech contractors and vendors who wish to use JPL images in 382 advertising or public relation materials should direct requests to the 383 Television/Imaging Team Leader, Media Relations Office, Mail Stop 384 186-120, Jet Propulsion Laboratory, Pasadena CA 91109, telephone 385 (818) 354-5011, fax (818) 354-4537. 386 \item Some image and video materials on JPL public web sites are owned by 387 organizations other than JPL or NASA. These owners have agreed to 388 make their images and video available for journalistic, educational 389 and personal uses, but restrictions are placed on commercial uses. 390 To obtain permission for commercial use, contact the copyright owner 391 listed in each image caption. Ownership of images and video by 392 parties other than JPL and NASA is noted in the caption material 393 with each image. 394 \end{itemize} 395\end{quotation} 396 397\subsection{DSS} 398\label{sec:ack:credits:dss} 399 400From \url{http://archive.stsci.edu/dss/acknowledging.html}: %, as of 2018-02-06. 401\begin{quotation} 402\noindent The Digitized Sky Surveys were produced at the Space Telescope Science Institute under U.S. Government grant NAG W-2166. 403The images of these surveys are based on photographic data obtained using the Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope. 404The plates were processed into the present compressed digital form with the permission of these institutions. 405 406The National Geographic Society - Palomar Observatory Sky Atlas (POSS-I) was made by the 407California Institute of Technology with grants from the National Geographic Society. 408 409The Second Palomar Observatory Sky Survey (POSS-II) was made by the California Institute of Technology with 410funds from the National Science Foundation, the National Geographic Society, the Sloan Foundation, 411the Samuel Oschin Foundation, and the Eastman Kodak Corporation. 412 413The Oschin Schmidt Telescope is operated by the California Institute of Technology and Palomar Observatory. 414 415The UK Schmidt Telescope was operated by the Royal Observatory Edinburgh, with funding from the 416UK Science and Engineering Research Council (later the UK Particle Physics and Astronomy Research Council), 417until 1988 June, and thereafter by the Anglo-Australian Observatory. 418The blue plates of the southern Sky Atlas and its Equatorial Extension (together known as the SERC-J), 419as well as the Equatorial Red (ER), and the Second Epoch [red] Survey (SES) were all taken with the UK Schmidt. 420 421All data are subject to the copyright given in the copyright summary\footnote{\url{http://archive.stsci.edu/dss/copyright.html}}. 422Copyright information specific to individual plates is provided in the downloaded FITS headers. 423 424Supplemental funding for sky-survey work at the ST ScI is provided by the European Southern Observatory. 425\end{quotation} 426 427 428%%% Local Variables: 429%%% mode: latex 430%%% TeX-master: "guide" 431%%% End: 432
